目的 探讨皮下植入式化疗泵在作胃肠肿瘤局部化疗时的并发症及预防措施。方法 对1996年1月至2001年6月收治的356例胃肠道肿瘤病人共植入化疗泵532个，包括动脉泵404个，静脉泵128个。其中植入1个泵250例，2个泵105例，3个泵24例。植泵后观察化疗泵作局部化疗时的并发症及防治情况。结果 356例病人中出现各种并发症62例，发生率为17．4％。其中早期25例，包括皮下积液、局部感染等。后期37例，包括导管不畅、导管堵塞等。结论 皮下植入式化疗泵的并发症多因操作使用不当引起。随着经验的增加，其并发症是可以预防的。

Complication of subcutaneous placement of chemotherapy pump in the treatment of the gastrointestinal cancer and its prevention

Objective To evaluate the complication of subcutaneous pla cement of chemotherapy pump in treatment of the gastrointestinal cancer and its preventio n. Methods From January 1996 to June 2001,532 chemother apy pumps inc luding 404 arterial pumps and 128 venous pumps were implanted in 356 patients wi th gastrointestinal cancer. One pump was implanted in 250 cases, 2 pumps were implanted in each of 105 cases, 3 pumps were implanted in each of 24 cases. The complication and its prevention were observed. R esults Sixty two patients developed complication among 356 patients ,the incidence being 17.4 %.In 62 cases, 25 cases were in early stage, which included hydrops of pump pock et , local infection ,etc; 37 cases were in advance stage, which included injec tion difficulty, catheter occlusion, etc.Conclusion Complication of subcutaneou s placement of chemotherapy pump often results from improper operation. Experien ce can reduce the complication.
